I'm going to go out on a limb and say that I've seen more of Pryor than anyone who is a member of this forum...outside of any other Buckeye fans here who live in Ohio.
Personally, I think he's a punk. On the field, he has, at a minimum, as much 'upside' as Cam Newton, and has played in MANY more big games than Newton. Is he going to be an NFL QB? Who knows? Everyone knows and pretty much acknowledges what type of "athlete" he is, but you'd all be surprised...the kid actually CAN throw a football, and with some decent touch too. I watched him make some pretty amazing throws during his time at OSU.
I'm guessing that most of the people here are basing their opinions of Pryor largely on what they're reading or hearing about his play from Sportscenter.
All that said, given his maturity level, I'm not sure Miami is a good place for him. As far as quarterbacks on our roster, I'd much rather see us spend time developing Devlin.
